Abstract
Abstract A method for updating a PLU file in a POS terminal. A slip having a dedicated format for printing data corresponding to a not-yet-registered article is prepared in advance of a retail transaction. When the not-yet-registered article is encountered during the retail transaction, a message is displayed on a display of the POS terminal to inform the operator that the particular article is not registered in the PLU file. The operator then inserts the dedicated slip into a print slot of a printer on the POS terminal in order to print article data (such as a message that the article is not-yet-registered, a code number for the article, a date and time for the transaction, and the like) thereon. The dedicated slip is handed over to the manager of the store who then updates the PLU file to include information (such as unit price and article name) for the not-yet-registered article.
